صحيح ابن خزيمه
Sahih Ibn Khuzaymah
جماع أبواب ذكر العمرة وشرائعها وسننها وفضائلهاChapters on Umrah, its Rulings, Sunnahs, and Virtues
(427) بَابُ الدَّلِيلِ عَلَى أَنَّ جِهَادَ النِّسَاءِ الْحَجُّ وَالْعُمْرَةُ،Evidence that the Hajj and Umrah are the equivalent of jihad for women.
Hadith Q3074
وَفِي الْخَبَرِ- عِلْمِي- دَلَالَةٌ عَلَى أَنَّ الْعُمْرَةَ وَاجِبَةٌ كَالْحَجِّ، إِذِ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَعْلَمَ أَنَّ عَلَيْهِنَّ الْعُمْرَةَ كَمَا أَنَّ عَلَيْهِنَّ الْحَجَّ
According to my knowledge, this hadith also proves that just as Hajj is obligatory, Umrah is also obligatory, because the Prophet Muhammad (peace be upon him) has clarified that for women, just as performing Hajj is necessary, performing Umrah is also necessary.
